FTRTA: Fault Tolerance and Reliable Transmissions Algorithm for IoT

Abstract

Features such as severe resource limitations, wireless communication media, network variable topology along with other IoT constraints, have led to increased faults and needs for fault tolerance guarantee in order to network correct performance. Accordingly, many studies have tried to improve this basic field by focusing on different techniques. But past methods are inefficient in stability guarantee and data exchange accuracy with the occurrence of error. In this paper, a method called FTRTA based on the development of RPL protocol and data distribution techniques has been introduced. Distribution techniques are effective in improving the balance of the network traffic load and fault tolerance. FTRTA has designed based on this technique and three operational steps. In the first step, the situation of network nodes is evaluated and analyzed in the same way as in the process of sending DIO messages. In the second step, the network communication graph is formed. Finally in the third step, data transmission is based on distribution technique with the aim of ensuring fault tolerance. The results of simulation using the Cooja software indicate high FTRTA performance in improving factors such as data delivery ratio and network throughput compared to similar studies.
